How to give connection to Radj?
Hello Navneet,
The CS+ and CS- are input terminals to an internal current sense amplifier. The current information is measured across a low-value sense resistor. The current sense resistor can be placed in the ground return path or in the positive output rail of the power supply VO as long as VO ≤ VDD. Normally most designs have these resistors of closer to 1K ohms chip resistor rated to 1/16W.
However, I would be able to guide you better if you can share more information about your design: input range, output voltage, and output power, etc.
Please refer to the attachment in the post below for Adj resistor connection.
Thanks,
Sonal
Vout from power supply.
Vout=12V
Iout=35A
Without adjusting the voltage, current sharing can be achieved.
Sense+ and sense - from the power supply module is not available.
Please suggest how can this IC be used.
Thank you.
Hello Navneet,
I am not sure what you mean by "Sense+ and sense - from the power supply module is not available." these signals are required to measure the voltage across the current sense resistor, what do you mean by it is not available.
Please have a look at the attached schematic which uses UCC39002 in a 12Vin and 2Vout/300A load sharing reference design example.
i am talking about voltage sense from power supply modules is not available.
(As shown in schematic sense+ and sense-)
Is it required to function the IC.
Hello Navneet,
The Controller requires that information to program the current sense amplifier internally.
Regards,
Sonal
